Description

Computer lock system

The present invention relates to a computer lock system, and more particularly to a computer lock system including a computer main body and a receiving antenna device externally connected to the computer main body.

[Conventional technology]

2. Description of the Related Art Conventionally, there is known a control method or apparatus for a processing apparatus that disables data input from a keyboard and a mouse when a specific user sits down while operating a computer or leaves the computer. An example of this is, for example, Japanese Patent Laid-Open No. 2001-268655 (Patent Document 1). This patent document 1 includes a computer equipped with an antenna, a portable information terminal (PDA), a mouse, etc., and communicates with the portable information terminal via an antenna connected to a short-range wireless communication interface built in the computer. The structure to perform is disclosed. When a specific user has a portable information terminal and is away from the computer and cannot communicate, data input such as a keyboard and a mouse is invalidated. When the portable information terminal is held and returned, it is automatically released and returned to a reusable state.

Another example is JP-A 2000-2222059 (Patent Document 2).
In Patent Document 2, in an information processing apparatus including a portable wireless tag (RFID card or the like) and an POS main body having an antenna, an authorized user leaves the POS main body without performing an operation end process or an interruption process. Data entry is prohibited. A configuration is disclosed in which data entry is allowed when approaching and unauthorized manipulation is prevented.

Still another example is JP-A-6-259160 (Patent Document 3). Japanese Patent Application Laid-Open No. 2004-228561 discloses an apparatus that can recognize an ID only by approaching a user having a transponder with a built-in individual ID by incorporating a receiver that receives ID information for receiving individual information in the computer main body.

However, there are weak points in such a safety system. For example, if a part of the safety system is frozen while the computer is not locked, it may be illegally used because it is fixed in the frozen state even though the proper unlocking radio signal has not arrived. .

As an example of freeze, an attack can be given to the program, but it is also conceivable to freeze other antenna functions. One example is disconnecting the antenna. This is because if the signal from the antenna is interrupted, it cannot be determined whether the proper source of the unlocking radio signal has gone out of the communication area or whether the wireless function has been impaired although it is within the communication area. This is because the signal from the antenna cannot be reached when the judgment is made based on the signal from the antenna. If this determination cannot be made, the computer lock status is fixed, and the computer can be illegally used even though it is actually out of the communication range.

To solve these problems, it is necessary to configure the system so that important parts of the safety system continue to operate even if some functions of the safety system fail.

<Overview>

As shown in FIG. 1, the computer lock system includes a computer main body 0100 and a receiving antenna device 0101 externally connected to the computer main body 0100. For example, a user who logs in to the computer and works (see FIG. 1 left diagram). When the user leaves the seat, the computer interface (display interface, etc.) is automatically locked (right figure in FIG. 1), and the user returns to the seat and approaches the antenna signal from the receiving antenna device 0101 when approaching. When the included lock release ID is received, the system is configured such that the lock is automatically released. In FIG. 1, as other hardware, a display 0102 and a keyboard 0103 used by the user during work are shown. The display screen on the left side of FIG. 1 shows a working screen, and the display screen on the right side of FIG. 1 shows a computer lock screen. In addition, the unlock ID may use a non-powered RFID owned by the user.
<Configuration of Embodiment 1>

As shown in FIG. 2, the computer lock system according to the first embodiment is a computer lock system including a computer main body 0200 and a reception antenna device 0210. The reception antenna device 0210 includes an antenna signal reception unit 0211, an antenna signal, and the like. The computer main body 0200 includes an antenna signal acquisition unit 0201, a determination unit 0202, an available status information holding unit 0203, an enabling unit 0204, an unusable unit 0205, and a control unit. 0206.
<Description of Configuration of Embodiment 1>
<Embodiment 1 Receiving antenna apparatus>

“Receiving antenna device” 0210 is externally connected to computer main body 0200, and a user who is logged in to the computer is present and working at a company or the like (the left figure in FIG. 1). If the user moves beyond the effective communication range with the receiving antenna device in FIG. 1), communication with the user who owns the unlock ID is not possible, and the computer is automatically locked. That is, the lock screen is displayed while the user is away from the seat as shown in the right diagram of FIG. When the user next approaches or returns to the seat, that is, when the user enters the effective communication range of the receiving antenna device, the unlocking ID owned by the user (for example, the card or wireless tag owned by the user) The computer is locked from the received antenna signal, and a lock release ID for releasing the lock from an unusable state is passed to the computer main body. An ID for recognizing itself from the antenna signal output unit of the receiving antenna device may be issued to the computer connected to the receiving antenna device.
<Embodiment 1 Antenna signal receiver>

The “antenna signal receiving unit” 0111 receives an antenna signal that may include noise and no signal wirelessly. As a wireless antenna signal, non-powered RFID, near field communication, or the like can be used. The received antenna signal includes noise and no-signal state, and includes the above-described unlock ID and the like.
<Embodiment 1 Antenna signal output unit>

The “antenna signal output unit” 0212 outputs the received antenna signal to the computer main body 0200. The output of the antenna signal output unit 0212 is input to the antenna signal acquisition unit 0201 of the computer main body 0200. The antenna signal may or may not include a lock release ID. The ID recognized by the connected computer may be output from the antenna signal output unit.
<Embodiment 1 computer main body>

The “computer main body” 0200 corresponds to a computer, a notebook PC, a tablet PC, or the like, and the display may be a display separate from the computer, or may be a lock of a display interface integrated with the PC. Computer work is a system that locks the computer without any setting even if you leave your seat during work in an environment where multiple users such as companies, city halls, public institutions, etc. are working. Yes. When the user returns to the seat, the unlocking of the computer is released when the unlocking ID possessed by the user is included in the antenna signal via the receiving antenna device 0210 externally connected to the computer main body 0200. can do. Here, the effective communication range (effective communication range) between the receiving antenna device externally connected to the computer main body and the user (having the lock release ID) is set within a range of 1 to 2 meters. In addition, it is convenient if the receiving antenna device is configured so that the effective communication range (effective communication range) can be changed by an operation from the connected computer main body. When transmission is used for receiving the unlock ID, the transmission intensity may be increased or decreased, and the reception sensitivity may be adjusted for reception. For example, when the installation interval of the computers is as narrow as less than 1 meter, the effective communication range (effective communication range) may be set to 1 meter or less.
<Embodiment 1 Antenna Signal Acquisition Unit>
The “antenna signal acquisition unit” 0201 acquires the antenna signal output from the antenna signal output unit 0212. The antenna signal acquisition unit 0201 acquires an antenna signal and a non-antenna signal as shown in FIG.
<Embodiment 1 determination unit>

The “determination unit” 0202 includes the antenna signal from the antenna signal acquisition unit 0201, or the display interface of the computer main body 0200 includes the acquisition unit signal that is a signal (non-antenna signal) that does not include the antenna signal from the antenna signal acquisition unit 0201. It is intermittently determined whether or not a lock release ID, which is an ID for making it normally available, is included.

As illustrated in FIG. 3, the acquisition unit signal described above includes an antenna signal and a non-antenna signal that does not include the antenna signal. As the form of the acquisition unit signal, there are a case of only the antenna signal (A) and a case of only the non-antenna signal (B). In the case of only the antenna signal (A), there are cases where only the lock release ID (A-1) is included, and the lock release ID (A-1) and other signals (A-2) are included. When both antenna signal (A) and non-antenna signal (B) are included, only unlock ID (A-1), unlock ID and other signals (A-1, A-2) are included. May be included.
The unlocking ID of the antenna signal (A) and other signals include an acquisition unit ID with antenna ID. Further, the non-antenna signal includes an acquisition unit ID without an antenna ID.
Here, the non-antenna signal includes a weak current generated at the reception antenna insertion port of the computer main body when the reception antenna device is not connected. Accordingly, the determination unit or each unit that uses the determination result of the determination unit is configured to continue functioning even if it is determined that the acquired signal does not include the antenna ID and part of the computer lock system is malfunctioning. Other signals of the antenna signal include a parameter changeable key for changing parameters of each unit such as a determination unit, an enabling status holding unit, an enabling unit, a disabling unit, and a control unit. You may comprise as follows. It is conceivable that the determination unit similarly determines whether the parameter change enabling key is included, and the parameter of each unit can be changed from the interface of the computer main body. The unlocking ID can be given as the parameter of the judging part, and the status itself, the valid period of the usable status, the history accumulation period of the usable status, etc. can be mentioned as the parameters of the available status holding part. As parameters of the enabling unit and the disabling unit, when there are a plurality of available status holding units, it is possible to list which available status holding unit is used as the available status or the unusable status. The case where there are a plurality of available status holding units means that there are a plurality of logged-in users registered in the OS (a usable file, a usable database, a usable external connection device, a usable network, Available applications are different). In this case, when Mr. A's unlock ID is acquired, the user can log in to Mr. A and use the computer itself in a normal manner, but use it so as not to affect other users' login. Is done. The parameter of the control unit is a case where the type of display interface to be controlled is selected. For example, when multiple displays are connected to one computer, you can configure normal operation for all displays, or normal operation can be performed only for some displays. This is a case where it is possible to select whether to configure. It is also possible to configure the display interface to be controlled according to time and time.

Since the determination unit 0202 intermittently determines an antenna signal or a non-antenna signal based on such an acquisition unit signal, even if the receiving antenna device externally connected to the computer body is removed, it is not affected. The computer can be locked and unlocked based on the acquisition unit signal.

For example, when the computer is locked and the display interface is in an unusable state, if the determining unit 0202 determines that the unlock ID is included, the enabling unit 0204 uses the available status information holding unit 0203. The available status information is used as an available status, and the computer is unlocked under the control of the control unit 0206. At this time, if the unlock ID is not included, the computer is kept locked. It is desirable that the operation of this determination unit is performed intermittently. The intermittent time interval is selected depending on the content of the work, but may be set in a time of several seconds to several tens of seconds for normal work. The computer main body may be provided with a time interval adjustment unit for adjusting intermittent time intervals.
<Embodiment 1 Available status information holding unit>

The “available status information holding unit” 0203 holds available status information indicating whether or not the display interface of the computer main body 0200 determined based on the acquisition unit signal is in a state where it can be normally used. The state in which the display interface can be normally used refers to a state in which data input and a work instruction by a mouse cursor can be performed using a keyboard or a mouse connected to the computer main body. However, since it is designed so that cursor movement and key operations for inputting a password on the lock screen can be performed even in a locked state, a state in which this operation can be performed is not referred to as a normally usable state.
<Embodiment 1 enabling part>

When the determination result in the determination unit 0202 includes a valid release ID, the “usage enabling unit” 0204 displays the available status information in the available status information holding unit 0205 as the display interface of the computer main body 0200. Is in an available status to make it normally available.
<Embodiment 1 Unusable part>

The “unusable part” 0205 displays the available status information in the available status information holding part 0203 on the display of the computer main body 0200 when the judgment result in the judgment part 0202 does not contain a valid release ID. The interface is set to an unavailable status so that the display cannot be normally used.
<Embodiment 1 control unit>

The “control unit” 0206 controls the display interface based on the available status information held in the available status information holding unit 0203. If the available status information is available status, the control unit 0206 performs control that allows the display interface to be used normally. If the availability status information is an unavailable status, the display interface is not normally used. A screen that is configured to be a lock screen, accepting the input of a password, and capable of being unlocked is not normally available. This is because the normal operation cannot be started immediately with the display interface having only the password acceptance function. However, the lock screen is not limited to this, and may be configured to be in a screen state that does not accept password input. In that case, it is configured not to accept mouse input, keyboard input, or cursor input.

In the computer lock system as described above, the reception antenna device 0210 is detachably connected to the computer main body 0200. Even if the reception antenna device 0210 is detached from the computer main body during the computer lock, the computer main body 0200 is described above. Since the antenna signal and the non-antenna signal are determined based on such an acquisition unit signal, safety can be maintained. In other words, it is possible to maintain safety without being affected by whether or not the receiving antenna device is detached from the computer main body.

Further, even if the receiving antenna device is replaced with another antenna receiving device, it cannot be used by a third party.
<Embodiment 1 Operation: Hardware Configuration (Computer Body)>

As shown in FIG. 4, the computer configuration of the computer main body includes a CPU 401, a nonvolatile memory 0402 such as an HDD and a ROM, a main memory 0403 such as a D-RAM, and an interface 0404. The nonvolatile memory 0402 stores programs such as an antenna signal acquisition program, a determination program, an available status information holding program, an enablement program, an disablement program, and a control program. Data includes an antenna signal, unlock ID, usable status information, and the like. These programs and data are read into the holding area of the main memory 0403 and executed in the work area. The interface 0404 includes a display interface 0405, a keyboard interface 0406, a network interface 0407, and the like.
<First Embodiment Process Flow Reception Antenna Device>

As shown in the right diagram of FIG. 5, the operation of the receiving antenna apparatus executes an antenna signal receiving step of receiving an antenna signal that can contain noise and no signal wirelessly by the antenna receiving program (step 0501). This antenna signal is a signal from, for example, a non-powered RFID. It is determined whether the lock release ID is included on the computer body side.

Next, an antenna signal output step of outputting the antenna signal received by the antenna signal output program to the computer main body is executed (step 0502). By this processing, the antenna signal is input to the externally connected computer main body.
<Embodiment 1 Processing Flow Computer Body>

As shown in the left diagram of FIG. 5, the operation of the computer of the computer main body as described above is an antenna signal acquisition step for acquiring the antenna signal output from the antenna signal output unit 0212 of the reception antenna device by the antenna signal acquisition program. Is executed (step 503).

Next, the display interface of the computer main body is made in a state in which the display interface of the computer main body can be normally used for the acquisition unit signal that includes the antenna signal in the antenna signal acquisition step 0503 or does not include the antenna signal in the antenna signal acquisition step. A determination step of intermittently determining whether or not a lock release ID that is an ID is included is executed (step 0504). Here, the intermittent determination operation is set in about several seconds to several tens of seconds in a normal operation.

Next, if the determination result in the determination step 0504 includes a valid release ID by the enabling program, the display interface of the computer main body normally displays the available status information in the available status information holding unit. An enabling step for setting the available status to make it available is executed (step 0505).

Here, the available status information indicating whether or not the display interface of the computer main body determined based on the acquisition unit signal by the available status information holding program is normally used is held. Therefore, the status is changed to the available status by the enabling step and is held. Further, the unlock ID and the login user information of the computer main body are held in association with each other. If there are multiple computer bodies, you can set the login cancellation ID individually. However, in an environment where the computer body is used in shared settings, you can use one lock ID for each other, A plurality of unlock IDs can be set. Furthermore, it is desirable to set another unlock ID to make it usable even when the user in charge of the computer main body rests at a company or public institution.

Next, when the determination result at the determination step 0504 is a determination result that does not include a valid release ID, the display status of the available status information holding step is displayed on the display interface of the computer main body 0200 normally. An unusable step for setting the unusable status for making the state unusable is executed (step 0506).

Here, when the ID is not the unlocking ID, it means that the locked state is continuously maintained when the locked state is established, and security measures can be taken for computers that are not associated with the computer main body. Therefore, the display interface cannot be used as it is. Such unusable state information is held in an available status information holding unit.

Next, a control step for controlling the display interface is executed based on the available status information held in the available status information holding unit by the control program (step 0507).

<Embodiment 4 Screen Saver Part>

A “screen saver unit” 0707 outputs a screen saver screen when there is no input from the interface for a predetermined time. Examples of the interface include keyboard input and mouse input. If there is no such input for a predetermined time, a screen saver screen is output. Usually, setting from several minutes to several tens of minutes is possible by user setting. When this screen saver is used for the purpose of locking so that the computer cannot be accessed without permission when the user is away from the desk, for example, it is likely to be set to about several minutes. For example, if the OS of the computer main body is a Windows (registered trademark) personal computer (Windows 10, Windows 8.1, Windows 7, etc.), the screen saver can be set by displaying the control panel screen and selecting Customize Desktop → Personal Settings. . If you check “Return to logon screen when restarting” on the screen saver screen, the screen saver is interrupted (for example, interrupted by interface input such as moving the mouse or performing keyboard key input). When you try to do so, you will be prompted to enter your password on the logon screen.
The screen saver screen will not be displayed if the screen saver is not set, so there will be no problem with this computer lock system. If the “Return to logon screen when resuming” check box is checked, there is a risk of conflict with the computer lock system, so it is necessary to consider the conflict between the operation of the control unit 0706 and the operation of the screen saver unit 0707. .
<Embodiment 4 Competition Adjustment Unit>

“The contention adjustment unit” 0708 gives priority to the operation of the control unit 0706 when the operation of the control unit 0706 and the operation of the screen saver unit 0707 compete. The operation of the screen saver unit includes both a screen saver screen display operation and a logon screen display operation when the work is resumed.

As shown in FIG. 8, the use of the interface when the operation of the control unit and the operation of the screen saver unit compete with each other will be described. The use of the interface in FIG. 8 is (1) when the screen saver is not activated, and (2) when the screen saver is activated but no password input is required.

When the screen saver section is OK and the control section is OK, the interface is OK. Even if the screen saver operation is NG (when the screen saver unit determines that the screen saver screen display operation or the logon screen display operation should be performed), if the control unit operation is OK, the interface use is OK and the control Part of the operation is given priority. Even if the operation of the screen saver is OK (when the screen saver determines that the screen saver screen display operation or the logon screen display operation should not be performed), if the operation of the control unit is NG, the operation of the control unit has priority. As a result, the use of the interface becomes NG. If the operations of the screen saver unit and the control unit are both NG, the use of the interface is also NG.

As described above, the computer lock system operates.
The other configuration is the same as the configuration of FIG.
<Embodiment 4 Action: Hardware Configuration (Computer Body)>

As shown in the left diagram of FIG. 10, the operation of the computer of the computer main body as described above executes the antenna signal acquisition step 1003, the determination step 1004, the enabling step 1005, the disabling step 1006, and the control step 1007. Thus, it is determined whether or not the unlocking ID is included in the acquisition unit signal as shown in FIG. 3 from the antenna signal acquisition unit 0701 (step 1004), and the enabling step 1005 and the disabling step 1006 are executed. The availability status information holding unit 0703 always holds the availability status or the unavailable status as availability status information. Since the processing from processing steps 1003 to 1007 is the same as the processing from processing steps 0503 to 0507 in FIG. 5 of the first embodiment, detailed description thereof is omitted.

In the state as described above, a screen saver activation timing determination step for determining whether it is a screen saver activation timing is executed (step 1008). As a result of the determination in the screen saver activation timing determination step 1008, in the case of the screen saver activation timing, the operation with the control program and the operation of the screen saver program compete with each other. . Here, the screen saver activation timing refers to the timing when the screen saver should be activated based on the judgment of the screen saver unit from the state where the screen saver is not activated, and the screen saver has already been activated and the operation of the screen saver is continued. It also includes the timing for determining whether to do so. In addition, the activation of the screen saver includes an operation of displaying a logon screen in addition to an operation of displaying the screen saver.

The screen saver activation determination step is executed to determine whether to activate the screen saver in response to the adjustment result in the conflict adjustment step (step 1010). When the activation state of the screen saver is recognized in the competition adjustment step, the screen saver step is executed (step 1011). In the screen saver step, the screen saver is displayed on the display or the logon screen is displayed on the display. If the screen saver does not start, leave it to the control of the control unit. After the screen saver is activated, or after leaving the control to the control unit, a use end determination step is executed (step 1012).

If the use end determination step does not determine the end of use, the process returns to the antenna signal acquisition step again. There are two ways to return to the antenna signal acquisition step when the screen saver is activated and to return to the antenna signal acquisition step without activation of the screen saver. The screen saver is activated when the control unit has made the display interface normally unavailable based on the unavailable status, which is the status in the usage status information, as long as the control status continues. The contention adjustment step is repeated to continue the screen saver in the activated state or to make the control state available to the normal display interface. When the determination unit determines that the unlock ID is included in the acquisition unit signal while the screen saver is continuing, the enabling unit changes the available status information to the available status, and accordingly, the contention adjustment unit Even if the screen saver release is not determined by the screen saver unit, the control of the control unit is prioritized and the contention adjustment is performed so that the display interface can be used normally. Accordingly, the screen saver activation determination determines that the screen saver has not been activated, that is, the screen saver has ended, and the display becomes usable in the normal usage state.

The above-described processing is repeated until the user finishes using the computer (step 1012).

As described above, according to the fourth embodiment, in addition to the first to third embodiments, for example, when a screen saver of a Windows (registered trademark) personal computer and a computer lock system compete, control of the lock system is given priority. User-friendly security can be maintained.
<Embodiment 5>
<Overview>

The fifth embodiment is a computer lock system having some features based on any one of the first to fourth embodiments.

The “password determination unit” 1108 determines whether the password is a correct password. Here, for example, if the computer body is a Windows (registered trademark) personal computer, the password is determined to be normal if it is the same as that set as the login password of the computer.
<Embodiment 5 Available status fixing unit>

The “usable status fixing unit” 1108 forcibly uses the available status information in the available status information holding unit 1103 when the judgment result in the password judgment unit 1108 is a judgment result that the password is a correct password. Fixed to possible status.
That is, if the password is normal, the computer lock system fixes the available status information in the available status information holding unit 1103 from the unavailable status to the available status. The display interface of the computer main unit becomes a normal usable state. The reason for this configuration is that emergency evacuation measures are required in the event that the source of unlocking ID is broken or the source of unlocking ID is lost. Therefore, it is preferable that this password is kept secret by a person with high authority such as a company system administrator. Also, if you use this password to unlock and then intermittently determine whether or not you have acquired an unlock ID, there will be a problem that the unlocked state can only be maintained for a few seconds. It becomes impossible to operate the computer. Therefore, when unlocking is performed using a password, normal processing such as acquisition determination of unlocking ID is stopped and the status of the always available status information is fixed to the available status. The other configuration is the same as the configuration of FIG.

As shown in the right diagram of FIG. 13, when the antenna signal reception step 1301 and the antenna signal output step 1302 are executed, the antenna signal from the reception antenna device 1110 is input to the computer main body 1100 that is externally connected. The processing of the antenna signal reception step 1301 and the antenna signal output step 1302 is the same as that of the antenna signal reception step 0501 and the antenna signal output step 0502 of FIG.
<Embodiment 5 Processing Flow Computer Body>

As shown in the left diagram of FIG. 13, the operation of the computer of the computer main body as described above executes an antenna signal acquisition step 1303, a determination step 1304, an enabling step 1305, an disabling step 1306, and a control step 1307. Thus, it is determined whether or not the unlocking ID is included in the acquisition unit signal as shown in FIG. 3 from the antenna signal acquisition unit 1101 (step 1304), and the enabling step 1305 and the disabling step 1306 are executed. The availability status information holding unit 1103 always holds the availability status or the unavailable status as availability status information. Since the processing from processing steps 1303 to 1307 is the same as the processing from processing steps 0503 to 0507 in FIG. 5 of the first embodiment, detailed description thereof is omitted.

In the state as described above, under the lock control of the control step 1307, a determination step is executed as to whether or not the display interface of the computer main body is in an unusable state in which the display cannot be normally used (step 1308).
